    LSX Performance Parts proudly offer the very best in piston development & innovation - Diamond Racing Pistons.

    Founded in 1968 by a group of racers named Jim "Diamond" Cavallaro, Nick Plantas & Butch Eldkins, The guys combined their resources & industry knowledge to create the perfect pistons set.

    It did not take long for the game changing brand to take off - In the 1970's Diamond was the go to brand for Super Stock & Pro Stock racing. As a team, Diamond was not focused on just supplying the very best pistons. They also did cylinder head porting, Engine building & race engine preparations. Diamond became contracted to NASCAR to builds all the engines for the IROC cars.

    Just a few years later, Diamond is far ahead of their time with the most innovative & succesful pistons on the market.

    Diamond is the biggest supplier of NASCAR, NHRA, Pro Stock, Drag Racing, Circle Track & Diesel markets.
